COMPANY, 1NcoR1o1a.A'.rnn,A n CORPORATION or DELAWARE s'roxm MEcHnN'IsM Application led May 25,

This invention relates to stoker mechanism and more particularly `to the distributing member therefor, and the principal object of the invention is the provision of a novel sectional distributor member that is provided with new and improved means for-connecting the sections together. Y

Another object of the invention is the provision of a new and improved distributor member having the portion that normally extends into the irebox of the locomotive entirely removable whereby the same may be readily' replaced. t

A further object of the invention is the provision of a novel sectional distributor member that is provided with new and improved means for attaching the sections together and for securing the members in posltion, whereby the forward section or thel entire member may be easily detached and readily removed.

A still further object of the invention is the provision of a sectional distributor member so constructed that only the forward section will be exposed to the intense-heat of the furnace, together with means for permitting the ready removal of said section.

Another object of the invention is the provision of a new and improved 'sectional distributor member that is cheap to manufacture, simple in construction, and one in which the end exposed to the heat `of the furnace may be readily and easily replaced.

Other and further objects and advantages of the invention will appear from the following description taken in connection with the accompanying drawings,in which Fig. 1 is a vertical section of a portion of a locomotive and a stoker therefor, showing my invention in position therein;

Fig. 2 is a section on line 2--2 of Fig. 1;

Fig. 3 is a perspective view of the rear section of the distributor member; and

Fig. 4 is a perspective view of the forward section of the distributor member.

In the use of locomotive stokers, the forward ends of the distributor plates are subjected to the intense heat of the rebox and as a result they burn 0E or are damaged to such an extent that they must be replaced 1929. Serial No. 365,878.

at intervals of from four to six weeks. Heretofore, it has been necessary to replace the .these dicuties by providing a sectional distributor plate in whichV the forward section may be'readily and easily removed or re-l placed, the parts being so constructed'that `they may be detachably hinged together whereby one man may replace aburnt-out section with a new one with a minimum amount of time and labor.

Referring now to the drawings wherein one embodiment of the invention is shown, the reference character 10 designates a locomotive having the backhead 11 provided with the redoor opening 12. The structure thus far described may be of the usual or any Well known construction, and further descrip-` tion or illustration is unnecessary.

A suitable Stoker 18 is provided for supplying fuel to the locomotive. The Stoker comprises a risericonduit 14 which extends upwardly and is curved forwardly for delivering the fuel through `the opening 12 onto a distributor plate 18'. The' conduit 14 is provided with a movable section 15 hinged at its lower portion as at 16 to the body of the conduit; The upper portion of the section 15 cooperates with the fredoor 17 for forming-a closure for the opening 12 when in theposition shown in Fig. 1 of the drawings. Access may be had to the firebox for hand firingby opening the door 17 and moving the` section 15 rearwardly about its hinge 16.

A sectional distributor member 18 is provided for receiving the fuel conducted u wardly through the conduit 14. The distributor member 18 is preferably in the form of a sectional plate, and comprises a rear secutor plate to the riser conduit 14. As shown,

' the lower wall 24 of the conduit 14 is provided with a recess or cut-away portion 25 into which is adapted to project the reduced portion 26 of the rear section 19, as clearly shown in Fig. 2 of the drawings. A pluv plate for holding the parts in assembled relation'. If desired the rear section 19 of the distributor plate may be provided lwith 'a set screw 34, which engages the lower surface of the plate for engaging the lower marginal Surface of the door opening for constituting a seat for the distributor plate. This screw may be adjusted to com ensate for sli ht variations in the dimenslons of the dierent parts. The rear section terminates adjacent to the inner wall of the backhead, wheby it is protected from the heat of the Suitable means are .provided for connecting the sections of the distributor member to ether. -As shown, the rear section is provided with openings 36, 37, adjacent to the forward edge thereof, that portion of the upper flat face 21 between theopenings 36,

and the forward edge thereof forming the pintles 38, 39, their lower surfaces being.

curved, as at 41, for this purpose. The forward section 22 of the distributor member is provided withhinge members 42, 43, which are curved for engaging the corresponding pintles 38 and 39. The parts are so constructedthat the meeting edges-of the two sections will form shoulders that engage after the manner of a butt hinge for limiting the downward movement of the front section below the plane of the upper surface ofthe rear section 19, but will permit the same to hinge upwardly and rearwardly for disenga'gmg it from the rear section after which it may be removed by sliding the same rear- .wardly on the rear section. The upper or free ends of the hinge members 42 and 43 terminate in the plane of the upper surface of the section, whereby, when the sections are assembled, they will be Hush with the upper surface of the rear section, as clearly shown in Figs. 1 and-2 of the drawings.

Suitable means are rovided for support.- ing the front section w ile-the same is being attached to the rear section.. As shown, the

. rear section is providedwith -a forwardly extending projectionor ledge` 44, which is downwardly oiset from the plane of the` re'ar section to form a support, as shown in tion, turning it overonto the rear section. .It

can then be removed from the fire-box. If necessary the forward section can be removed .and .another inserted in its place without drawing the fire, thereby elfectmg a great saving of time in makin replacements.

The projection or le ge 44 may abut the lower portion ofthe front section toassist in supporting the forward section, but since it merely forms a shoulder-or abutment for this v purpose it lneed extend into the fire-box only a short distance, and consequently is not likel ly to become hot enough to burn oif.

The forward section 22' is provided with air passages 4.5, 46, extending horizontally therethrough. These passages align with an air passage 47 -in the rear section.

The forward section 22 is provided with curved channels 48 for directing the fuel lat-` erally, as is usual in such constructions.
